The synthesis of SACs has been significantly advanced due to the enormous efforts devoted into the area. Atomization, contrary to other methods, is a very attractive and innovative top-down approach to achieve high density supported active sites with outstanding stabilities. However, few attentions have been paid to this area despite there are significant advances achieved in the past two years. In this short review, we detailly discussed the latest advancement of atomization for SACs synthesis and highlight the advantages and opportunities.
